Subject: [PATCH v7 2/4] riscv: dts: fix the icicle's #pwm-cells

From: Conor Dooley <conor.dooley@...rochip.com>

\#pwm-cells for the Icicle kit's fabric PWM was incorrectly set to 2 &
blindly overridden by the (out of tree) driver anyway. The core can
support inverted operation, so update the entry to correctly report its
capabilities.
